A loud crash from downstairs.

Sans jolted out of bed, his right eye flickering. "Papyrus!" In a blink of an eyesocket, the short skeleton is downstairs. "Paps! Are you okay-"

He stopped and noticed the hole that their front door had once occupied. He rolled his eyes, immidiately knowing who the culprit culprit was. "Undyne-"

"NGAHHHHHHHHH!" The ex-head of the royal guard towered over him. Sans just glared at her. "Morning, Bonehead! I'm just here to talk Papyrus into entering some fancy dance competition with Mettaton, Alphys and I are entering. And maybe get some spaghetti. I'm starving, man."

"Monsters are allowed to join?" Sans asked, surprise written all over his skull. She nodded eagerly and shoved her phone right into his face. "A ballet competition?"

Undyne smiled proudly, showing off her pointy set of teeth. "Mmmhmm! Frisk would've joined, but they're apparently 'too young'." She made air-quotes with her fingers.

"What is the tiny human too young for?" Papyrus asked, peeping out of the kitchen. Sans' pulse sped up upon seeing his apron stained red, but just as quickly calmed down when he realised that it was just sauce. Just sauce.

"'Sup, Papyrus!" Undyne nodded. "Check it out!"

"Wowie!" Pap clapped, his gloves muffling the sound. "Can we really go to My-lane?"

"It's Milan." Undyne said, rolling her eyes. "And of course we can go. Are you in or not?"

"I'm in!" Papyrus announced eagerly. "Sans, will you be fine alone?"

"I'm not going to be alone." Said skeleton responded quietly, his left eyesocket flickering blue as he fixed the door for what seems like the hundredth time with magic. "I'm going with. I'm enterin' too."

He slowly turned to face them, not at all surprised when they go speechless. He was, however, surprised when Undyne lunged at him and gave him a noogie. "That's the spirit, nerd!" She crowed maniaclly. "It was really lame of you to quit dancing. Now this, this is not lame." Her smile was huge.

"Please do not noogie the skeleton!" Papyrus warned. He somehow managed to pull his brother out of Undyne's grasp and proceeded to envelop him in a bone-crushing hug, his feet dangling in the air. Sans smiled and relaxed into the hug, comforted by how warm and alive his brother felt.

"I have to tell Alphys!" Undyne announced, doing a 360° and running out- breaking the down the door in the process.

"Undyne!" The short skeleton screamed.
